Scale
Resize parts in your model, which is useful when working with an imported model that is associated with a different default unit system.
Apply a Variable to a Parameter
Apply a variable to a parameter, or create a new variable on the fly from a tool microdialog.
You can apply existing variables and add new ones via the microdialog in various sketch and geometry tools.
- You can also create a variable by entering a new name and expression in the
                        microdialog’s text field, for example: 
Variable1=50 - In addition, you can also create a new variable based on an existing
                        variable, for example, 
Variable2=Variable1*0.5.
